IMPROVEMENT m WASHING-MACHINES.

Specification forming part of Letters Patent No. 176,736, dated May 2, 1876; application filed December 17, 1875.

' To all whom itrmay concern:

Be it known that I, CHARLES CAMPBELL, of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part whole length across the convex surface of the cylinder, the said rollers held against the cylinder bymeans of arms pivoted at their middles to a spring-supported bearing.

To enable others skilled in the art to make and use my invention, I will-describe its construction and operation.

In the drawings, Figure 1 is a side elevation of my device; Fig. 2, a cross-section;

Fig. 3, an end view.

A is the cylinder; B, the slats or strips covering or forming its convex surface; 0, a cloth or flap, one end of which is fastened across the convex surface of the cylinder at D;

E, the axis of the cylinder; F, the crank or handle by which the cylinder is revolved; G G, fluted rollers, the ends of the axes of which are secured in springs H, which are elastic, and which springs are pivoted or secured at their middle to the uprights of the J J J J scalloped) secured at their ends to an elastic self-adjusting bearing, which. is accomplished by the following means: The cross-arm K is pierced by and slides loosely'uponthe vertical standard L, and is sustained by the spiral springs M. Upon the ends of this arm K are second cross-arms N N, pivoted at their middle to the ends of the arm K, and at their extremities supporting the ends of the axes of the rollers J J J J. O is a hole through the bottom of the frame, through which to pass a rod, wire, or other security, to fasten the machine onto the bottom of a tub of water.

The operation of the machine is as follows:

I set the machine in a tub containing water surface of the cylinder, the cloth being laid down upon the clothing. Commencing at and proceeding upward from the point D, as the clothing is laid on the cylinder A is revolved in a direction downward from the point D, and, when all is ready, the cylinder is revolved as rapidly as is desired, the springs H and M keeping the fluted rollers against the cloth 0 with a gentle pressure. The clothing is thus being constantly soaked and pressed by the flutes asit dips into water immediately below the point D, when in place in the tub. The spaces between the slats B permit the water to circulate through the clothing and into the interior of the cylinder.. By pushing up spring M from the bottom and inserting a pin in the standard L, to keep the spring there, the pressure of the rollers J J J J can be regulated. By moving the height of this pin difierent pressures can be obtained. The cloth or flap C'protects the clothing bein g washed from wearing friction from the rolls,-but does not preclude the pressure of these rolls from having its proper effect.

1 Where the clothing is'heavy, its effect, as well as of all projecting parts, is, when it reaches the rollers, to press the first one back, but it will be seen that this does not interfere with the rest, as any one or more may be depressed, but the remaining ones will retain their position. The forcing down of one does not tend in any great degree to force the other up, as, by the cross-arm K, arms N, and springs M and H, each one is independent in its action, while they all have a common bearmg.

L, is large enough, or so slotted as to permit this arm to be sogged down on one side or the other with ease.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-.-

In a washing-machine the combination of The opening in arm K, to admit standard a revolving cylinder, acloth 0r fla-p attached pivoted at their nfrieldles to a spring-supported at one of its ends to said cylinder to hold bearing, 'su bstanti'ai ly as set forth. the clothing to be washed between it and the cylinder, and four spring-rollers im- M CHARLES CAMPBELL. pinging their whole .length across the con- Witnesses: vex surface of the cylinder, the said rollers W.
